Another observation is that axis Z only works in Velocity 1-45 in the motor tuning but the other motors works from velocity 1- about 150 and if I drive the Z axis in velocity 15 I can stop the axis by hand that is impossible with the other axis.

I now tried to load the roadrunner g-code and the Z axis worked until the speed was to high than axis locked and started to shake. If I shift the motor output pins from Z to A the problem moves to A. So I guess it something with step pin 7 and dir pin 3.

I have now tried two different 25-pin cables and another computer but the problem is still there, but after I have tried some different settings the problem has moved from axis Y to Z. So now All axis works perfect except Z Which just shakes sometimes and works nice sometimes.

Yes it might be the 25-pin cable or the port of the computer I will check that tomorrow. But thanks a lot for the help. I saved a lot of time for me. I am really glad this works so fine now. But now I must sleep in other wise I will turn in to a zombie. Bye bye

Ok good to here that, I have tried around in the tuning now and the dir pulse doesent seem to make any changes on any axis. The step pulse 1-3= Y bad and the other god. Step pulse 4-5 = Y good and Z a little jumpy.

If you should be honest is Nema 23 good or not so good stepper motors?

I mean the driver test that comes with mach3, Well when I change it to 4 and 4 Y axis works realy nice but the Z axis starts to jump little now and than, is there a way to change it for just one axis instead of all?

OK, can I try the port with the test software and see if that gives me any information?
